A licensed dentist may delegate to a competent dental hygienist those procedures over which the dentist exercises full responsibility, except those procedures that require professional judgment and skill in diagnosis, treatment planning, or the cutting of hard or soft tissue. The board of dental examiners may adopt rules governing the scope of practice of dental hygienists.
